Abstract (en)

An optical system that includes a first curved-surface mirror having an opening or a transmitting portion, a second reflecting portion including plural reflective surfaces that divides the light flux from the opening or the transmitting portion, and configured to reflect light fluxes resulting from the dividing by the respective reflective surfaces, to respective positions different from one another on the first curved-surface mirror, a third reflecting portion having plural reflective surfaces which reflect the light fluxes that have resulted from the dividing by the second reflecting portion and have been reflected on the first curved-surface mirror, and a fourth reflecting portion having plural reflective surfaces that reflect the light fluxes from the third reflecting portion. The number of reflective surfaces of each of the third and fourth reflecting portions is the same as a division number in the dividing of the light flux by the second reflecting portion.
